JUIIUS JUDELSON, OF `\1\|'1E'W YORK, N. Y'.

DBEB..

Application filed April 18, 1921.

To all whom t may concern.:

Be it known that JULIUS J UDELsoN, citizen of the United States, and resident of the city of New York, in the county of Bronx and State of New York, has invented certain new and useful Improvements in Driers, of which the following is a speciication.

This invention relates to drie-rs. More particularly this invention relates to driers wherein the clothes or materials to be dried are held in a drying chamber where the moisture is evaporated therefrom.

One of the objects of this invention iS to provide a drier of the character described with eflicient and practical means for holding the materials in the drying cabinet and for readily removing the materials therefrom.

Another object is to provide a drier of the character described with a drying rack and supporting frame and guide therefor which shall be economical of floor and drier space.

A further object of this invention is to provide in a drier of the character described a drying rack and frame for loading and unloading the materials to be dried which may be readily moved in and out of the drier cabinet and adapted to be totally located therin so as to aiford a compact and neat cabinet.

ther objects of this invention will in part be obvious and -in part hereinafter pointed out.

Certain features herein shown and. de-

scribed are shown described and claimed in my co-pending applications for Patent Serial Nos. 458,314 and 462,323, filed respectively in the UnitedStates Patent Ofice the 4th day of April, 1921, and on the 18th day of April, 1921.

With the above exceptions the invention accordingly consists in the features'of construction, combinations of elements and arrangement of parts which will be exemplicd in the construction hereinafter described and of which the scope of invention will be indicated in thefollowing claims.

In the accompanying drawings in which is shown one of various possible illustrative embodiments of this invention,

Fig. 1 is a perspective view of my improved drier, showing the rack carrying frame and one of the racks pulled out of the cabinet ready for loading of said rack with material to be dried; and

Fig. 2 is a vertical section of my invention Serial No. 462,324.

taken through one of the racks vertical and vhorizontal central portions of the device being omitted in order to show the'remainder on an enlarged scale.

F 1g. 3 is a detail partial section of the heater chamber cut along line 3-3 of Fig. 2. `.Referring in detail to the drawing, A ind icates the drying cabinet'co'mprising the side walls 10, vrear walls 11 and the top 12. The rear walls 11 are made preferably of two independent sheets of metal 13 and 14 so as to enclose the air space 15 therebetween and suitably jointed to each other at the side edges thereof as at 16. rlhe top 12 comprises the sheets 22, 23 enclosing the .air space 24 therebetween; and the side walls (not shown 1n detail) are of similar double-wall constructlon. For holding the sides 10 together and for maintaining the rear walls 11 in close contact with said sides, suitable means such as the transversely disposed straps 29 l are provided. The ends 40 of said straps are twisted at right angles to the body thereof and terminate in downward extending hooks 41. On the inner faces of the side walls are attached the strap catches 42 adapted to receive the hooks 41.

Heat is supplied to the cabinet by means u of a suitable heater .52 which may be arranged outside of said cabinet the heated air being conducted through a chamber 53 located near the bottom of the cabinet and having baffle plates 54 forretarding the heat Lvehicle in its passage through the chamber before escaping through the flue 55.

For exhausting much of the moist air from the inside, of the cabinet during the drying operation, a suitable vent box 56 having openings 57 on one side thereof is interposed in said flue 55. A ,hinged door 58 may be arranged at .the front of the cabinet for allowing access to the heating chamber 53.

The apparatus for loading and unloading the materials into and out of the cabinet and holding the materials in place willA now be described. The means employed for this purpose comprises a rack member having a door 43 at one end thereof, the member 44 at the other end thereof and horizontal cross bars 45 suitably connecting said door and said end member.

A frame 50 is adapted to support the front end of said rack member, the horizontal guides 49 and 49 secured to the upper and lower ends of said frame respectively being arranged to telescope into the drying cabinet in a manner hereinafter described. A trolley 46 is secured to the end member44 of the rack while a similar trolley 47 is secured to the outside of the door 43. Wheels such as 61 and 61. are secured to the trolleys 46 and 47 respectively and serve to suspend the rack from the horizontally disposedy trolley guides 48 and 49 respectively. When the door 43 is in closed position the strain is taken off the wheel 6l which is rigid with the `plate 47 by the member 66 which has a wedge portion 67,.which rests normally on the member 68 of the door frame. This Wedge portion 67 is cut away obliquely at the end to give a cam face 67a so that when the door is moved out the cam face rides over the member v68 and drops down, thus carrying the wheel 61. down with it into contact with the guide 49.

For allowing the frame 50 to be moved from its outermost to itsA innermost position where it will be out of the way during the drying operation and where it occupies an inapprecia'ble area of floor space, the guides 48 and 4,8 are made hollow to receive the guides 49 and 49 respectively. A bushing 63 is provided at the front end of each of said guides 48 and 48 while a wheel 64 is rotatably secured near the rear end of each of the guides 49 and 49 which are thereby constrained to move horizontally in and out of said guides 48 and 48. f

ICasters such as 5l are suitably secured to the lower end of said frame 50 as vloy means of the angle brackets 65, said castors resting on the floor and serving to take up the stress due to the weight of said frame and the racks supported thereby from the vguides 48 and 48 when said frame is in its outermost position.

By reason of the above described arrangement, it will be seen that the frame 50 may be moved horizontally independently of the movement ofthe rack so that if desired, said frame may be maintained in its outermost position at all times in which event only the rack is moved into the cabinet for drying the material placed thereon. However, it will be obvious that the frame 50 may also be moved readily inwardly out ofthe way, when desired after or simultaneously with the inward movement of said rack. It will be apparent that the rack and frame may be moved in and out of the cabinet in one operation if desired by taking hold of the handle 69 and frame simultaneously.

The function and operation of the rack and frame in connection with the drying cabinet will now be clear. The frame 50 is first pulled out from the inside of the cabinet, the rods 49 and 49 being withdrawn from the rods 48 and 48 respectively, the castors 5l rollingalong the Hoor, while said frame is being moved. The rack may now be readily withdrawn from the cabinet by pulling on the handle 69 whereby the trolley Wheels 60 and 61 roll on thefguidesl 48, 49

`respectively until the end 44 is stopped by `used heat vehicle then escapes through the vent 55 while the moisture from the cabinet is drawn out through the vent openings 57.

It will thus be seen that there is provided apparatus in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention I claim as new and desire to secure by Letters Patent l. In a drier, a cabinet having an opening in one end thereof, a drying rack movable in and out of said cabinet, an end member on said rack fo'r sealing said opening in the outermos-tl position of said rack, and a frame for supportin said rack and movable in and 'out of said 'ca inet independently of and together with said rack.

2. In a drier, a dryingcabinet, a rack slidable inand out of said cabinet, means in said cabinet for supporting one end of said rack and a frame slidable relatively to said cabinet independently of said rack for supporting the other end of said rack.
